Nesting complex systems
… discusses an artistic method of engaging with complex systems. The engagements take the form of inserting a certain something (an object, a task, a conversational prompt, myself) into a complex system with well-defined and elaborate technical processes serving specific and declared goals. The …

Quantum mechanics in complex systems
… laser fields, also lay corrections to the systems due to relativistic effects. Dimensional scaling calculations with relativistic corrections for systems: H, H<sup>-</sup>, H<sup> 2-</sup>, He, He<sup>-</sup>, He<sup>2-</sup>, He<sup>3-</sup> within super-intense laser fields were …

Synchronization transitions in complex systems
… wird im Bezug auf die Symmetrien des Systems untersucht. Es wird gezeigt, daß die durch die Symmetrien verursachte Reversibilität des Systems nichttriviale topologische Eigenschaften der Trajektorien bedingt, so daß das als dissipativ konstruierte System in einem ganzen …

Language : a complex-systems approach
… redefines language in the holistic terms of a complex-systems approach. Language is the outcome of the dynamic interaction between social and physiological systems -- particular attention is paid to consciousness. Neither language, society or culture is an 'object', but is created through the …

Architecting complex systems for robustness
… by organizations to develop robust and reliable complex systems. The intent of robust design is to create systems that are insensitive to variations from production, the environment, and time and use. While this process is effective, it can also be very time consuming and resource intensive for …

Aging processes in complex systems
… understanding of physical aging in nondisordered systems with slow, i.e. glassy-like dynamics. In many systems a single dynamical length L(t), that grows as a power-law of time t or, in much more complicated cases, as a logarithmic function of t, governs the dynamics out of equilibrium. In the …

Cyber Maintainable Safety-Critical Complex-Systems
… the growing threat of cyber-attacks on control systems. Whilst the convergence of Operational and Informational Technology becomes essential, the traditional security approach has proven inadequate in addressing the unique challenges faced by such industries. As a result, Cyber Resilience is …

Network Optimization of Dynamically Complex Systems
<p>The aim of this research is to optimize large scale network handling capabilities for large system inventories and to implement strategies for the purpose of reducing capital expenses. As computers become more and more networked, it is easier to share files among storage media. In addition, more …

System Governance Analysis of Complex Systems
… of this research was to develop and deploy a systems-based framework for analysis of complex governance systems using a multimethodology research design. Two research gaps motivated this research: (1) lack of an integrated conceptualization of a system governance construct, (2) an absence of …

Modeling complex systems with differential equations
… specifically dynamical processes of real-world systems. <br>Solely relying on mathematical <br>formalism, it has become possible to make adequate predictions of <br>the temporal evolution of systems of all kind and furthermore to control <br>processes from outside. <br>However, despite the fact …

The robust design of complex systems
… be difficult and time-consuming because of the complexity of most design problems. It is the goal of this thesis to introduce methods which reduce problem complexity and so make the application of Robust Engineering Design (RED) methodology easier for large design problems. By drawing from …

Contextualising user interfaces for complex systems
… that people have in interacting with complex, computer-based systems. The fields of intelligent and adaptive interfaces and agent-based systems are surveyed and critiqued to identify how intelligent human-computer interfaces can be used to improve interaction. The need to manage …

User experience design of complex systems
… of consumer-facing products, services, and systems. The result of these methods was a series of findings that supports the notion that a holistic "systems-based" approach offers competitive advantages to organizations looking to successfully implement a design-oriented strategy. It is this …

Framework for optimizing survivability in complex systems
… survivability at risk. Maximizing resiliency in complex systems can be viewed as a multi-objective optimization that includes system performance, survivability, economic and social factors. Systems requiring high survivability: a hydroelectric dam, typically require one or more redundant …

Analysis and dynamic modelling of complex systems
… physics with its rich experience in modelling complex systems could play a much more important role than that of an ancillary science.<br>In the following, different biological systems are investigated in order to reach a model based understanding. This mathematical description then helps in …

A multidisciplinary approach to complex systems design
The design and management of organised systems, comprised of dynamic interdependent collectives of autonomous agents, is the kind of problem that the discipline of complex systems is intended to address. Nevertheless, conventional model-based applications of complex systems may be of limited …
